Application filed October 20, 1917. Serial No. 197,679.

To all whom it may concern:

Be it known that I, GEORGE P. BUCHANAN, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Bulb Removers and Replacers, of which the following is a specification.

This invention relates to a bulb remover and replacer and has for its primary object to provide a construction of this character positive in operation and composed of few parts substantially connected.

An'object of the invention is the novel manner in constructing the clamp members and associating the same with the remaining parts of the replacer so that a bulb may be quickly and effectively clamped, and in such a manner that different size bulbs may be accommodated. 1

With these and other objects in View the invention will be better understood from the following detailed description taken in connection with the accompanying drawing wherein Figure 1 is a side elevation of the device.

Fig. 2 is a vertical sectional view.

Fig. 3 is a front elevation.

Figs. l and 5 are detailed views.

Fig. 6 is a view illustrating the connection of the handle extension.

Fig. 7 is a detailed view of a modified form of clamp.

The numeral 1 designates a handle provided adjacent one of its ends with a slot 2 and a circular opening 3 that communicates with the slot and opens at the extreme end of the handle. Spaced at intervals along the handle are eye screws 4: mounted so as to slidably support an operating rod 5 one end portion of which is bent at a right angle and arranged in the slot as indicated at 6. This right angle bent portion 6 is provided with openings that receive rivets 7 which in turn pivotally support clamp members 8 and 9 of identical construction. Each member consists of a single length of wire 9 bent to have limbs 10 slidably mounted in the opening 3 and a central portion 11 that engages the bulb, and if found advantageous in practice this portion 11 may have mounted thereon a sleeve of rebers apart in the upward movement of rods When it is necessary to increase the length of the device I provide a handle extension 1 1 having a ferrule 15 slidably engaging one end of handle 1.

Also slidably mounted upon the extension 14 is a rod 16 having a detachable connection with the rod 5 as indicated at 17 When the bulb is to be removed the rod 5 is slid vertically and this movement of the rod 00- operating with the pin 13 causes the members 8 and 9 to move in a direction away from each other until such a position is reached as to allow the bulb to be arranged between the members. After this operation the rod 5 is moved downwardly which movement through'the cooperation between the limbs 10 and the walls of the opening 13 causes the members to move toward each other and effectively clamp the bulb.

From the foregoing description taken in connection with the accompanying drawing, it would be apparent that I provide a device which is admirably adapted for the purpose for which it is intended, that the device is simple, durable and eiflcient of construction, and that the device may be manufactured and sold at a comparatively low cost.

Having described my invention what I claim is:

1. A bulb remover and replacer comprising a handle formed with a slot having a circular opening communicating with the slot, a rod slidably mounted on the handle and having a right angle portion slidably mounted in the slot, a pair of clamping members each having a portion passing through said opening and pivoted to said right angle portion and a pin spanning the opening and arranged between the clamping members for the purpose set forth.

means passing through the handle and located in position to holdsa'id members apart when moving said rod in one direction, the mounting of said members being such as to allow the members to move bodily vertically. In testimony whereof I affix my signature.

GEORGE P, BUCHAN AN.

2. A bulb remover and replacer comprising a hollow handle, a pair of clamping members each having an extremity arranged Within the handle, a rod slidably mounted 5 on the handle and having one end bent at an angle and pivotally connected to the mentioned extremities of said members and Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patenta, Washington, D.
